Answer: 10%
Explanation:
Given: Previous Hourly pay= $7.00
Current Hourly pay = $7.70
Increase in hourly pay = Current Hourly pay - Previous Hourly pay
= $7.70- $7.00
= $0.70
Now, the percent increase in her hourly rate of pay will be :

Hence, the percent increase in her hourly rate of pay = 10%
Answer:
The true statement is that different gases with the same mass and temperature always have the same average kinetic energy. This is one of the postulates of the kinetic theory of matter.
If we two objects A and B, they will have mass mA and mB and velocity vA and vB respectively. If K.E = 1/2mv^2 . Then it follows that
1/2mAvA = 1/2mBvB. Since the mass is the same it means the velocity of the two objects should be the same so that they have the same average kinetic energy.
Subsoil: This layer has normally less organic matter than the A horizon, so its colour is mainly derived from iron oxides. Iron oxides and clay minerals accumulate as a result of weathering. In a soil, where substances move down from the topsoil, this is the layer, where they accumulate.
